The City of San Diego is marking a key milestone in efforts to repair and resurface streets citywide – 250 miles of slurry seal work during the fiscal year that ended June 30.

Completion of the multi-month project in the South Bay made fiscal year 2024 one of the most productive years for road-resurfacing in over a decade, underscoring the city’s commitment to investing in infrastructure.

Work will continue in the coming year, with the budget for fiscal year 2025 allocating $104.7 million for overlay reconstruction projects and $35.3 million for slurry seal, which will fund another 225 miles of overlay and surface seal projects.

“We’re making record investments in road repair to address years of insufficient investment that have left these critical public assets in bad shape,” said Mayor Todd Gloria. “San Diegans deserve safe and smooth roads, and this milestone demonstrates our continued commitment to improving streets and neighborhood infrastructure in every community.”

In addition to the slurry seal work in Nestor, teams from the City’s Transportation Department and contracted crews this week have projects under way in Serra Mesa, Navajo, Pacific Beach and Peninsula.

“Completing this many slurry seal miles is a year long process requiring hard work and careful planning from staff and our resurfacing partners,” said Transportation Director Bethany Bezak. “We appreciate the support from all of our San Diego communities and look forward to continuing our robust paving program into the new fiscal year.”

Slurry seal is a cost-effective pavement preservation method that extends the life of streets already in good condition by 5 to 8 years. Slurry seal is used to prevent the deterioration of streets, which is vital to improving the overall condition of San Diego’s 2,800-mile road network. It reduces the need for a more costly asphalt overlay and reconstruction for badly deteriorated streets. Asphalt overlay, a more intensive type of road repair, requires larger investment; between design, planning and construction, overlay

The $104.7 million will provide funding to complete 75 miles of asphalt overlay, as well as the design and planning needed to complete 105 miles in FY26.

San Diego’s transportation department also has two in-house mill and pave teams that rehabilitate roads to help protect the structural integrity of damaged streets, but in shorter sections than the asphalt overlay process.

Recently, the city implemented two new street resurfacing methods – cape seal and scrub seal – which, similar to slurry seal, extend the life of roads by filling cracks, protecting against moisture incursion and minimizing the development of potholes and other surface deformities.
